sqlite3_value_text() always returns UTF8. UTF8 cannot contain a zero-valued byte that is not a zero-valued character. I think you're actual question is if zero-characters are prohibited, and I think the answer is no. Values returned by _text() are always zero-terminated, but I'm not sure there is anything stopping you from entering a string with a null character in the middle (assuming you pass in an explicit length to sqlite3_bind_text()). In any event, you can use sqlite3_value_bytes() to find out the length of the text value returned. That is, however BYTES, not CHARACTERS. -j -- Jay A.
